Product Description

Unlock the full power potential of your mini racer with the Pro Circuit Platinum Head Pipe. Directly inspired by the legendary, championship-winning Works pipe, the Platinum series delivers identical horsepower and torque gains across the entire RPM range while offering superior environmental protection. This premium expansion chamber is the ultimate upgrade for aggressive young riders who need a broader, more hard-hitting 2-stroke powerband to clear track obstacles and pull holeshots ahead of the competition.

Constructed from rugged, stamped AKDQ high-quality carbon steel, this head pipe features precision hand-welded and pounded seams for optimized internal fluid dynamics. What truly sets the Platinum pipe apart is its unique, advanced nickel bath plating technology. This process fuses a durable protective coating to the high-strength steel structure, providing exceptional resistance to abrasion, rock dings, and rust. Complete with an embossed classic logo nameplate, a precision CNC-machined exhaust flange, and reinforced mounting brackets and stingers, this pipe is engineered to survive the most punishing motocross tracks.

Frequently Asked Questions

Q: Does this Platinum head pipe require jetting changes to the carburetor?
A: Yes, because Pro Circuit pipes significantly increase exhaust scavenging and airflow efficiency, you will generally need to adjust your carburetor tuning. We highly recommend checking Pro Circuit's official jetting chart for your specific elevation, temperature, and fuel type to prevent running lean.

Q: Will this Pro Circuit head pipe bolt directly up to my motorcycle's stock OEM silencer?
A: Yes, this pipe is specifically engineered with factory dimensional tolerances, allowing it to seamlessly mount to your stock silencer or any matching Pro Circuit slip-on silencer.

Q: How do I clean and maintain the nickel-plated finish after a muddy ride?
A: Unlike unplated raw metal pipes that require constant oiling to prevent rust, the Platinum pipe's nickel finish can be washed with standard soap and water. Avoid using harsh steel wool or abrasive pads that can scratch the plating material.

Expert Pro-Tip: When installing your fresh expansion chamber, always use brand-new exhaust manifold O-rings and a fresh copper crush gasket at the cylinder face. Reusing worn-out seals allows unburned oil and exhaust gases to spray over the front of your engine casing, creating a messy cleanup and causing a minor pressure drop that can soften your low-end throttle response. For an absolute air-tight seal, apply a thin bead of high-temperature RTV silicone around the pipe flange before slipping it into place.
